So last night I was having contractions that took my breath away but they weren't close enough to go in. Last night I also threw up twice. In the last 27 hours I have only eaten 2 slices of pizza (which I threw up), 1 pop tart and a bowl of Ramen noodles. I've continously drank lots of water between that time. I cannot seem to eat without throwing it up or just feeling nauseous. I'm not sure what to do! :(
